SHANK non TURN sHoEs.

' a specification.

This invention'relates to vshanks for turn shoes.

An object of the invention is to provide a metallic shank adapted to be secured upon the upper surface of the sole of a shoe with interlocking engagement therewith,V whereby longitudinal or` lateral displacement of thestiifcner is prevented.

Another object of the invention is to provide a novel and ei'licient means for securing a metallic shank between thesole and the liningr of a shoe, so that all of said parts will maintain their proper relationship irrespective of the strains to which the shoe 'is subjected when worn.

@ther objects will appearl from the following description. reference being made to the drawing in which- Fig. l is a longitudinal vertical sectional view of the shoe sole having my invention embodied therein.

Fig. 2 is an inverted plan view of the metallic shank.

Fig. 3 is a cross sectional view on the line 3 3 of Fig. l.

Fig. 4 is a side elevation of a preferred form of the invention.

My improved shank is preferably Iliade of metal or metallic alloy and comprises a plate of a length sufficient to have its rear end resting upon the shoe heel a considerable distance behind the breast wall of .the heel and its forward end terminating approximately at the break line of the sole.

I prefer, though I dov not limit myself to, a construction in which the rear end of the plate is near the'rear wall of the heel and in which the side edges of the heel portion of the plate` are near the side edges of the heel and in which the side edges of the plate` intermediate of its ends, have a contour conforming approximately to the contour of the shank of the shoe sole.

In the form of the invention shown the plate comprises a heel portion 1 having a hole 2 therein; a shank portion 3 and a widened front end portion 4 terminating ap* proximately at the break line of the shoe in which the stiifener is placed. An integral portion 5 ofthe plateextendsy rearwardly intothe hole 2 toward the rear end thereof, making the' hele 2 substantially U-shaped. In side elevation the shankportion jis arcuate (F 'l and 1l) conforming to the shape ofthe shank or arch of the shoe in which theishank isplaced so that the shank will function to maintain the arch of the i shoe permanently in the desired shape. rllhe device is preferably made of sheet metal and in the `use of such material the sheet metal is crimped to provide on its under side and midway between its side edges a longi tudinal depending flange 6 of a vertical width less vthan the thickness of the outer sole of the shoe. The extended portion 5.,. the shank portion 3` and the front end 4f are formed with tongues 7. of which those on the extension project upwardly and those on the shank portion 3 and the front end et project downwardly.

As shown. the shank may be embodied in ak shoe by forming a groove in the sole 8 in which the flange 6 is placed. the tongues 'i' oir the shank portion 3 and on the front end 4- being forced into the sole, while the projections 7 on the extension 5 are `forced into the member 9 of the shoe. The nails l0 are forced through the member 9, through the hole 2 and downwardly through the heel portion of the sole 8 and into the shoe heel. The hole 2 also provides an opening through which the fastening tacks 11 pass in the preliminary assembling ofthe parts comprising the sole 8, the metallic shank and the member 9 of the shoe. The member 9 terminates slightly in advance of the breast wall of the shoe heel and forms a smooth support for the lining 12.

The construction shown and described prevents relative displacement of the parts, so that the shoe will retain its original shape under the strains and stresses of wear.

I do not restrict myself unessentially, but y what I claim and desire to secure by Letters Patent is 1. A shoe comprising a sole having a longitudinal groove in the upper side of a portion thereof, a metallic plate having side and end portions of approximately uniform thickness resting upon the top of the sole. a projection rigid with the under side of said plate fitting closely in said groove and terminating short of said end portions of said plate leaving said end portions bearing upon the top of the sole across the ends of said projection, and means for securing said parts in said relationship.

2. A shoe comprising a sole having a longitudinal groove in its upper side for a portion of its length along the shank thereof. a metallic plate having a side and end portions ot approximately uniform thickness throughout the length and width thereof resting upon the top ot the sole at the sides and beyond the ends of said groove, a project-ion rigid with said plate fitting closely in said groove throughout the length or" said projection, and means for securing said parts in said relationship.

3. A shoe Comprising a sole having a longitudinal groove in the upper side of the shank portion thereof, a metallic plate oonorming substantially tothe shape of the shank portion of the sole(` a longitudinal flange extending downwardly from said plate and terminating short of both ends of said plate and fitting closely in said groove leaving the smooth side and end portions of said plate resting .ipon the sole at the sides and beyond the ends of said groove` and a number of tongues integral with said plate engaging in said sole.

il. A shoe comprising a sole having a longitudinal groove in the upper side of the shank portion thereof, a metallic plate conforming substantially to the shape of the shank portion of the sole7 a longitudinal flange extending downwardly from said plate and terminating short;- of both ends of said plate and fitting closely in said groove leaving the smooth side and end portions of said plate resting upon the sole at the rsides and beyond the ends of said groove, a

number of tongues integral with said plate engaging in said sole, a lining supporting portion upon the heel portion of said plate beyond the rear end of said flange, and al lining having its rear portion upon said supporting member and resting directly upon said plate in front of said supporting member.

5. A shank Jfor turn 'shoes comprising a metallic plate of a length sufficient to eX- tend from a point behind the breast wall ol: the heel of the shoe 'for which the shank is intended to a point near the break line of said shoe and having a hole through the rear portion thereof, and a longitudinal depending flange integral with the under side of said plate and terminating between the ends thereoic for engagement in a groove in a shoe sole.

6. As iank for turn shoes comprising a metallic plate of a length suflicient to eX- tend from a point behind the breast wall oi the heel of the shoe for which the shank is intended to a point near the break line ot said shoe and having a hole through the rear portion thereof, a longitudinal depending flange integral with the under side of said plate and terminating between the ends thereof, and means in connection with said plate for engaging a shoe sole at the sides of said flange.
